Contemporary music is a category of cultural capital that is employed by symphonies and opera especially inefficiently. Considering its quantity, presumed relevance to social needs, and programming, this is surprising. The authors present a model of the programming decision for an ensemble that indicates that increasing the use of contemporary music's capital stock (i.e., increasing on-stage performances of contemporary music and thus listeners' exposure to and appreciation of it) is more difficult than in other artistic fields. Since redirecting audience attention to this cultural endowment will require retiring many resources from common use, standard recommendations for subsidies should be reassessed.  相似文献

Objectives. To document criminality, psychiatric difficulty, IQ, EQ, and EI amongst Irish, male juvenile detainees (Detainee Group). To compare their IQ, EQ, and EI to non‐offending boys attending a child psychiatry clinic (Psychiatric Group) and boys without offending or psychiatric problems (Community Group). To compare psychiatric morbidity between the detainee and psychiatric groups. Method. Criminality levels of 30 detainees were evaluated using official court charge sheets. Psychiatric status was assessed through structured clinical interview (DISC‐IV); IQ through an individually administered IQ‐scale (WASI); EQ using the BarOn EQi:Youth Version (EQi:YV); and EI using the MSCEIT: Youth Version – Research Edition (MSCEIT:YV‐RE). IQ, EQ, and EI levels in the psychiatric and community groups were compared. Psychiatric morbidity between detainee and psychiatric groups were compared. Results. A total of 335 crimes led to the detention of detainees. Eighty‐three percent of detainees had a psychiatric disorder compared to 60% of young people in the psychiatric group. Detainees had 3.1 disorders each compared to 1.4 disorders in the psychiatric group. A total of 63.3% of detainees had an externalizing problem, 37.9% an internalizing problem, and 66.7% a substance dependency or use problem. A total of 21.4% of detainees had an IQ score below 70. The detainee and psychiatric groups had similar deficits in EI and significantly lower EI than the community groups. Conclusions. Serious levels of criminality and psychiatric disorder exist amongst Irish detainees. They have significantly lower IQ than young people attending a psychiatry clinic and both share deficits in the ability to accurately identify emotions, use emotions to guide thought processes and to prioritize thinking and to effectively regulate emotions.  相似文献

The universality of human nature determines the universality of values and its particularity determines the diversity and plurality of values that is the fundamental determinant of security problems among different value systems. In a narrow sense, value security refers to a situation in which value concepts of a state, region, or a nation, social class are not under threat from the external adversaries, which is called conceptual value security. In a broad sense, value security refers to the consistency between the system of realistic value security and that of conceptual value security. National value security encompasses both value security in a nation-state and security of national values, in which the former is featured by the recognition and acceptance of a prevailing value in a nation-state, and the latter is characterized by the sovereignty of national values. Due to the fact that the issue of value system is a meta-theoretical one and the security of conceptual value system is part of cultural security, value security holds a core position in cultural security and is an important component of overall national security system. Additionally, value security embodies the security of value pursuits and value criteria in different spheres of the overall national security system and therefore, it is also an indispensable and flexible support to the overall national security.  相似文献

ABSTRACT

As is true for most legislation, the Fair Housing Act (FHA) was a product of its time; the legislation’s content, and even passage, was formed by dominant issues in housing markets and the country at that time. The context shaped the goals of the FHA and the strategies and tools employed under its auspices. Fifty years after the passage of the FHA, much of that context has changed. This commentary argues that changes in the context not only raise new fair housing challenges and create new gaps in our knowledge, but also may necessitate a fresh look at fair housing strategies and tools if they are to be effective at achieving the goals of the act. This commentary begins with a brief background on the FHA itself, the social context at the time of its writing, and its main goals. Next it lays out a few key changes in housing markets relevant for fair housing, highlighting challenges they may create and where research could be of greatest value. It then considers challenges arising from threats to two specific U.S. Department of Housing and Urban Development (HUD) fair housing rules seen by many as critical fair housing tools. The commentary ends with two examples of a “refresh,” where current context has shaped, or reshaped, a strategy to address today’s fair housing challenges.  相似文献

ABSTRACT

There are strict laws relating to alcohol intake and driving; however, while most people are aware of these laws, drink driving still occurs. The current research provides an in-depth account of individuals’ awareness and attitudes towards current drink driving limits and laws in England. Individuals (N?=?83) were interviewed, and their responses recorded for thematic analysis. Results indicated major themes of: attitudes towards drink driving laws, limits, and effectiveness; reasons for drink driving; and post-drink driving reflections. Outcomes show that most individuals are aware there are strict laws, but are unaware of the exact limits, and do not understand how to convert legal limits into actual drinking behaviours. Sub-themes emerged indicating that individuals held heuristic beliefs about being able to consume one or two alcohol beverages without negative effects on their driving ability. Conclusions from this research indicate that views are mostly invariant across key population demographics; peer pressure was the only sub-theme that appeared to differ between younger and older individuals. The findings have implications for policy makers and future interventions in terms of clarifying drink driving limits and translating this into drinking behaviour. There was also some support for stricter laws and regulations.  相似文献
